AB - Five novel one-dimensional cerium(III) carboxylate coordination polymers, [Ce(O2CCH2CHMe2)(3)(EtOH)(2)](n) (1), {[Ce(O2CCH2Me)(3)(H2O)]center dot 0.5(4,4'-bpy)}(n) (2; 4,4'-bpy = 4,4'-bipyridine), {[Ce-2(O2CCHMe2)(6)(H2O)(3)]}(n) (3), {[Ce-3(O2CCHMe2)(9)(nPrOH)(4)]}(n) (4), and {[Ce-3(O2CCHMe2)(9)(HO2CCHMe2)(2-)(H2O)(2)]center dot 2Me(2)CHCO(2)H}(n) (5), showcase the surprisingly consistent tendency of Ce(III) coordination network structures to adopt one-dimensional connection modes. The type of carboxylate as well as the reaction solvents determines the exact bridging versus end-on coordination modes for the carboxylates and, in turn, discriminate between linear, zigzag, and helical arrangements. Detailed magnetochemical analyses reveal pronounced single-ion effects and the expected weak antiferromagnetic coupling.
